Patented Aug. 18, 1931 UNETED STATES HUGH W. CHRISTIE, OF TULSA,OKLAHOMA GAS BURNER Application filed May 10,

This invention relates to burners of the type employing a series ofplurality of burner jets which are all connected to a source of gassupply.

The primary object of this invention is to provide a device of the abovementioned character, having an auxiliary pipe extension foraccomplishing more complete carburation of the burning fluid or gas.

A still further object of this invention, is to provide a device of theabove mentioned character, which is detachable from the main gas supplypipe and which is supported thereon by means of an extension secured tothe gas supply pipe which is received 1n one of the carburating pipes ofthe burner nozzle.

A still further object of this invention, is to provide a device of theabove mentioned character in which two gas carburating tubes areconnected to two gas burner jets in a normal manner in order that theflames emanating from the jets will be offset from the main gas supplypipe thereby aiiording a greater heating area than if the burners werein single longitudinal alignment with the main gas supply pipe.

lVith the above and other objects in view that will become apparent asthe nature of the invention is better understood, the same consistsinthe novel form, combination and arrangement of parts hereinafter morefully described, shown in the accompanying drawings and claimed.

In the accompanying drawings wherein like reference characters indicatecorresponding parts throughout the several views,

Figure 1 is a top elevational view of: the burner showing the relationof the auxiliary carburating device connected to the burner jets;

Figure 2 is a side elevation of the invention further showing thearrangement of the carburating pipes secured to the burner nozzle;

Figure 3 is a side elevational view of the invention showing the mannerof supporting the carburating tube and the auxiliary carburating tubeupon the main gas supply P 1 1929. Serial No. 362,088.

Figure 4 is a cross-sectional view taken on lines l4l of Figure 2 andshowing the manner in which the auxiliary carburating tube is connectedto the main gas supply pipe and to the burner jet;

Figure 5 is an end elevational View e1nbodying the invention partly incross-section showing the burner assembled in relation to themain-supply gas pipe;

Figure 6 is a similar view partly in cross section taken on line 66 ofFigure 2 showing the relation of the gas burner supply pipe and itsnozzle to the auxiliary carburating tube;

Figure 7 is a cross-sectional view taken on line 77 of Figure 2 showingthe means for clamping the carburating tube and burner nozzle to themain gas supply pipe; and

Figure'8 is a cross sectional view taken on line 88 of Figure Qfurthershowing the clamping device or means for holding the carburating tubesupon the main gas supply pipe and also showing the air vent. in theauxiliary carburating tube.

Referring more in detail to the accompanying drawings which shows thepreferred embodiment of the invention, there is illustrated a main gassupply pipe 5, which may be of any desired length upon which is securedor formed bosses 6 and 6 for receiving burner nozzles orjets 7 and 7'.It will be noted that the bosses 6 are smaller in diameter than thebosses 6 which are formed in a manner for the purpose of receiving themain carburating tube and the auxiliary carburating tube which will belater described.

The main carburating tube 8 is provided with a plurality of air openings9 for ad mitting air to the gas jets 7 whereby a mixture is carburatedand formed for passage to the burner jets 10. The burner jets 10 are setforth in Patent 1,67 9,298 and are described in more detail therein. Thelower end of the main carburating tube 8 is secured to themain gassupply pipe 5 by a machine screw 11 which engages the boss 6 and holdsthe carburating tube 8 securely in place. The auxiliary carburating tube12 which forms the most important part of this invention, 100

is also similar to the carburating tube 8 and is provided with openingsfor the passage of air 13, for commingling with the gas emanatingthrough the pipe or jet 7 The auxiliary carburating tube 12 is merelysuspended above the boss 6 and is provided at its upper end with anextension 14 which has its end communicatively secured to the upperportion of the main carburating tube 8 which is the termination thereofand also to the central portion of the pipe 15 which con nects theburner jets 10.

It may be stated that the gas jets 7 and 7 are screwed into the main gassupply pipe 5 and are provided with the usual openings at the upper endthereof designated by the reference characters 16 and 16.

It is to be understood that any number of the burners including the maincarburating tubes 8 and the auxiliary tubes 12 may be secured to a maingas supply pipe 5 if desired and which is usually the custom inconnection with this type of heating devices.

As shown in the drawings, the main gas supply pipe 5 is screw threadedas at 17 to receive gas pipe fittings to a gas main or the like, whilethe opposite end is shown 7 closed as at 18, it may be opened andextended to any desired length upon which the bosses 6 and 6 and the gasjets 7 and 7 may be secured.

It has been found in common practice by providing an auxiliary gas jetwith an auxiliary carburating tube mounted thereover communicating witha similar carburating tube and gas jet, that better results are obtainedand a better carburating mixture is formed for burning in the burningjets.

It is to be understood, that variations in size and arrangement of thecarburating tube may be resorted to without departing from the spirit ofthe invention or the scope of the sulojoined claims.

I claim I 1. In a gas burner of the character described, a main gassupply pipe, spaced gas nipples secured to the main gas supply pipe,

a gas burner supported over the nipples, said gas burner including amain and auxiliary operating tube having their ends surrounding thenipples at the junction with the pipe.

2. A gas burner comprising a pipe having aboss, spaced nipplescommunicating with the interior of the pipe one of them being locatedupon the boss, a tubular member snugly receiving the boss and havingopenings at the upper portion of the nipple thereon, a second tubularmember surrounding the other nipple and having openings, tubular membersbeing connected together at their upper ends and the first mentionedtubular member having a pair of spaced outlet nozzles located at itsupper ends. 7

In testimony whereof I affix my signature.

HUGH W. CHRISTIE.
